Mediterranean nutrition: a model for the world?

The protection of Mediterranean populations against ischaemic heart disease has been recognised ever since the "Seven Countries" Study by Keys. It is probably related to the life style and, in particular, to the dietary habits of these populations. The Mediterranean diet is characterised by a certain frugality, a low intake of saturated animal fats contrasting with a high but reasonable intake of mono or polyunsaturated fatty acids, slow carbohydrates, fresh vegetables rich in antioxidating vitamins, fish and wine. These dietary habits have been shown to improve the lipid profile (not only lowering LDL-cholesterol but also raising the HDL-cholesterol), platelet activity and to reduce the phenomena of lipoperoxidation. The roles played by garlic and onions are controversial. Nevertheless, at pharmacological dosages, they have cholesterol lowering, fibrinolytic and antiaggregant effects. These dietary habits, which have been proved to be beneficial, should therefore be preserved in our country.
